Title
(EN) GRAFT EQUIPPED WITH STENT
(FR) GREFFE MUNIE D'UNE PROTHESE ENDOVASCULAIRE
Abstract
(EN) A graft equipped with a stent, including a plain-woven tube of a polyester resin fiber, having a wall thickness of 20 to 100 $g(m)m and disposed on both inner and outer surfaces of a stent comprising a flexible wire having a support framework comprising zig-zag wires, wherein the inner and outer surfaces of the tube are partially bonded to each other by a polyester resin. The graft does not prevent a blood flow due to kink and constriction at bent portions such as arcuate portions, curved portions and zig-zag portions, is highly resistant to extension/contraction and bending, and can be easily adapted to the shapes of the blood vessels of the human body. Since the graft is a thin artificial blood vessel, it can be inserted into a sheath having a small diameter, can be used for complete percutaneous intravascular surgery, is free from leak of the blood from its connection portion with the blood vessel and can be retained inside the body with the stent not in direct contact with the living body.
(FR) L'invention porte sur une greffe munie d'une prothèse endovasculaire consistant en un tube à tissage croisé de fibres de résine de polyester aux parois d'une épaisseur de 20 à 100 $g(m)m sur les surfaces intérieure et extérieure duquel est disposé un fil élastique porté par une structure de fils en zigzag, les surfaces intérieure et extérieure du tube étant partiellement liées par la résine de polyester. La greffe ne produit pas de constrictions ou de rétrécissements s'opposant au passage du flux sanguin dans les parties recourbées telles que les arrondies, les courbes ou les zigzag, présente une forte résistance à la dilatation/contraction et à la torsion, et s'adapte facilement aux formes des vaisseaux du corps humain. Comme la greffe est un petit vaisseau artificiel, elle peut s'insérer dans une gaine de petit diamètre et peut s'utiliser pour une intervention intravasculaire percutanée complète, elle est de plus exempte de fuites au niveau des raccords avec les vaisseaux sanguins, et peut rester dans le corps car la prothèse endovasculaire n'est pas en contact direct avec les tissus vivants.
